COMBINED LETTER S-HEET AND ENVELOUPE.

SPECIFICATION forming partof Letters Patent No, 346,620, dated August 3, 1886.

Application tiled September 26, 1885. Serial No. 178,255. (No model.)

To all whom t may concern:

Be it known that l, THEoDoRn O. L. SoHRA DER, a resident of New York city, in the county and State of New York, have invented an Improved Combined Letter Sheet and Envelope, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, in which- Figure l represents a face View of the blank constituting my improved letter sheet and envelopc. Fig. 2 shows the face view of the Fig. 3 is a back view of the same when'folded together.. Fig. 4 is a cross-section on the line c c, Fig. 2, but on a much larger scale than the remaining iigures.

This invention has for its object to construct acombined letter sheet and envelope in one piece, so that one address only will have to be written.

Merchants and others having a large correspondence lose much time by writing the address for each letter on the envelope, and also on the letter-sheet. By myinvention this will be avoided, and, nevertheless, when the letter is sealed a package is produced which answers every purpose of a sealed letter, being even able to have folded into it memoranda or slips, which cannot fall out of lthe sealed envelope.

In the drawings, the letter A represents the entire blank of which I make use in forming a let-ter sheet and envelope. The upper portion of the blank forms a letter-sheet, and is divided by ,imaginary or other lines, a b, into three sections, d, e, .and f ,but a smaller or greatery number of sections may be used, if

desired. Below the lowermost section, f, is ,Y

the envelope-section, g, which has projecting sideflaps, h h, and a projecting face-flap, t', and which section g has an opening, j,

through its greatest extent. The flaps h and i should be gurnmed. The Writer will put the address on the top section, d, as shown in Fig. l, and will then write the rest of the letter on theremaining sections, and will nally fold the sections one upon another, as in Fig. 4, and then fold the naps h and i' over the whole package, as in Fig. 8.

The envelope-section g, where it is perforated with the opening j, will lie just over the section d, to display the address written thereon through the opening j, asin Fig. 2. When the letter is opened, which is easily done by cutting the ilaps h andi where they are folded, the address will again be found at the top of the letter, and on it also the postage-stamp and the stamp of the post-office, thus making the letter a more perfect record of its conveyance and delivery'than is the case With the letters which are separated from their envelopes. y

The dotted lines It 7c in Fig. l show that the sheet may throughout be made as wide as the lower section, g,"with its 'flaps h. In this case the sides lo k of the letter portion are folded 'upon 'the flaps d e f before these are folded together. The section g may, if desired, be made without the iiap t', as in many cases the iiaps hh will suffice to seal the letter.

A combined letter sheet and envelope made in one piece of several sections, d ef, ,for the letter portion, and of the section g for the envelopeportion, the section g having sealingliaps a d the ccntralopening, j, substantially as andfor the purpose specified.
